OverviewReactive oxygen species (ROS) and reactive nitrogen species (RNS) often have a negative connotation due to their oft-cited presence in cell damage, apoptosis, and disease. However, many of the molecules involved in the formation of these ROS/RNS are actually beneficial under normal physiological states. An improved understanding of the balance between the molecules involved in ROS/RNS formation and their resultant metabolites is necessary. This session will highlight tools and the latest biotechnological efforts for ROS/RNS detection.
